Yes I would have to agree. My standard built diffs are now in Aussie "rough as guts mate", even after a strip down and rebuild, using same parts.
Thus time to order some new balls and rings for the 502X. My 201 has had many more runs and the diff is still very acceptable. Wonder why the 502X got such a bad set of balls?
